We can use holograms for cars in several ways: for cars paint and car displays. In this blog post, we will explore what these applications are and how they work.
Holograms on Car Paint
With holograms, car surfaces can have different colours or patterns depending on how the light hits them. For example, a car can have a rainbow effect or a metallic shine when viewed from different angles.
How does this work? Holograms must first be recorded on a special piece of film. Next, we can use this film to create holograms on car surfaces. Holograms in car paint can create different patterns and colours depending on the angle and intensity of the light source. They can also change with the movement of the car or the observer. Some examples of holographic car paint are:
- The Lamborghini Aventador LP 700-4 Pirelli Edition features a thin red stripe along its body that turns into a Pirelli logo when viewed from certain angles.
- The BMW i8 Concept Spyder has a silver-blue paint that shifts to turquoise-green under different lighting conditions.
- The McLaren Speedtail has a carbon fibre body with titanium oxide particles that reflect light in different colours.
The advantage of using holograms on car paint is that they can create unique and eye-catching effects that can enhance the aesthetic appeal of the vehicle. However, there are also some drawbacks. For example, scratches or abrasions can easily damage holograms on car paint. Another one is that they can cause unwanted reflections or glare that can affect visibility or safety.
Therefore, if you want to use holograms on your car paint, you should make sure that you use high-quality materials and techniques and protect your car from external factors that can harm it.
Holograms on Car Displays
Another way to use holograms is through car displays. This means that the car’s dashboard or windshield can show three-dimensional images or information that appear to float above or beyond them. For example, a car can show navigation directions, traffic alerts, pedestrian detection, or entertainment features as 3D overlays:
The Continental 3D Lightfield Centerstack is a screen technology that uses liquid-crystal technology with LED backlighting and a diamond-like diffuser to create a 3D look without glasses or eye tracking. The screen also features haptic feedback and can display various types of content, such as navigation maps, media controls, climate settings, etc.
The Funai Electric Holographic Touch Display is a screen technology that uses a screen-mounted flush with the top of the instrument panel that appears to create a HUD that hovers above the dash. The display can also support touch interaction and can show various types of content, such as speedometer readings, traffic alerts, phone calls, etc.
The Envisics AR-HUD is an augmented reality system that uses laser-based holography to project visuals that seem to appear in front of the car. The system highlights pedestrians, stalled vehicles, or turn-by-turn directions as 3D overlays. It can also provide a bridge to self-driving cars pointing out specific hazards that require human drivers to retake the wheel.
The advantage of using holograms on car displays is that they can provide immersive and interactive experiences that can enhance the functionality and enjoyment of driving. They can also improve safety by highlighting potential hazards or warnings in real-time. However, there are also some challenges. One of them is ensuring compatibility and standardization across different devices and platforms. Another one is ensuring reliability and durability under various environmental conditions.
Conclusion
Holograms are not just science fiction anymore. They are becoming a reality for cars as well. We can use holograms for aesthetic and functional purposes, such as creating different effects on car paint or showing 3D information.
